HUB.

SPECIFICATION forming part of Letters Patent No. 689,308, dated December 17, 1901.

Application filed July 31 1901.

Be it known that 1, CHARLES DAVID HEVE- NOR, a citizen of the United States, residing at Salamanca, in the county of Oattaraugus and State of New York, have invented a new and useful Hub, of which .the following is a specification. 1

The invention relates to improvements in hubs.

The object of the present invention is to improve the construction of hubs, more especially the means for attaching the same to an axle, and to dispense with nuts and washers,

ficient construction of great strength and durability designed for use on wagons, carriages, and analogous vehicles and adapted to enable oil to be employed for lubricating the same.

Afurther object of the invention is to provide a device of this character which will afford a dust-proof bearing and which will enable a wheel to bereadily removed when desired without the use of a wrench or similar tool.

The invention consists inthe construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a longitudinal sectional view of a hub and one end an axle constructed in accordance with this invention. Fig. 2 is a transverse sectionalview of the same. Fig. 3 is a side elevation of one end of the axle, illustrating the arrangement of the sleeve which constitutes the axle-box and which is detachably interlocked with the hub.

Like numerals of reference designate corresponding parts in all the figures of the draw lugs.

l designates a sleeve forming an axle-box and arranged on a spindle 2 of an axle 3 between inner and outer bands 4 and 5, which may be constructed in any suitable manner nal movement. The bands 4 and 5 may be fixed to the axle in any suitable manner, and they permanently secure the sleeve to the spindle and dispense with the use of washers,

Serial No. 70,410. (No model.)

which become soon worn and which when worn cause the wheel to wabble. vBy obviating the necessity of employing washers the durability of the vehicle is greatly increased.

' The outer faces of the bands'are slightly tapered to fit a-removable hub 6, which has its outer 'end closed and which fits snugly against the inner bandor collar 4, wherebya dust-proof bearing is afforded. The sleeve which forms the axle-box is provided 'at one side with a longitudinal enlargement or key 7, and it has a longitudinal recess 8, located at a diametrically opposite point and adapted to receive a spring-actuated block or bar 9, which is mounted in a recess 10 of the hub. The hub is provided at one side with a longitudinal groove 11 to receive the key or enlargement 7, and the recess 10 is located at a diametrically opposite point,

The block or bar fits into the recess 8 of the sleeve and locks the hub on the axle and holds the axle-box rigid with the hub. The key or enlargement also prevents the hub from rotating independently of the sleeve, and it thereby relieves the locking device of strain. The block is held in engagement with the sleeve by a bowed spring 12, interposed between the hub and the block or bar and having its ends engaging the latter and provided with a central opening, through which extends a stem 13, passing tlirougha perforation of the hub and having a threaded inner end 14, which engages a threaded socket of the block or bar. The stem is provided at its outer end with a head, and it is adapted to be drawn outward to withdraw the block or bar from the recess of the sleeve. Vhen the block or bar is withdrawn into the recess of the hub, the latter is adapted to be moved longitudinally and may be readily withdrawn from the axle. The hub is also adapted to be readily replaced, and it is unnecessary to remove the same except'for repairs. The axle is provided with a longitudinal oil-passage arranged at an inclination, and this passage 15, which consists of a bore or opening, extends from a point beyond the inner collar or band at the top of the axle to the bottom of the same at the center of the spindle. An oil-cup 16 is mounted on the axle and is provided with a suitable valve for controlling the flow of the oil. By this construction the axlemay be continuously lubricated or it may be lubricated as desired.

It will be seen that the device is exceedingly simple and inexpensive in construction, that it is adapted to increase the strength and durability of wheels and axles, and that it affords a dust-proof bearing. It will also be apparent that it dispenses with n u t-s and washers and enables the wheel to he lubricated Without removing it from the axle and that while the wheel maybe readily removed it need only be removed for repairs.

The hub may be constructed of wood, metal, or any other suitable material, and when constructed of wood its interior'will be provided with asuitable metallic lining to receive the rib or flange 7. and the block or bar 9, and I desire it to be understood that these and various other changes within the scope of the appended claims may be; resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

.Vhat I claim is--- 1. In a device of the class described,'the combination of a spindle, a sleeve forming an axle-box and permanently mounted on the spindle, and a hub det-arhably interlocked with the sleeve at a. point between the ends of the spindle and receiving the sleeve and adapted to be removed without detaching the sleeve, substantially as described.

5 2. In a device of the class described, the combination of a spindle provided at its ends with suitable stops fixed to it, a sleeve located between the stops and arranged on and extending longitudinally of the spindle and forming an axle-box,said sleeve being adapted tachably interlocked with the sleeve and receiving the same and adapted to be removed without detaching the sleeve from. the spindle, substantially as described.

at. In adevice of the class described, the combination of a spindle, a sleeve'forming an axle-box and permanently mounted on the spindle and adapted to rotate, said sleeve being provided witha recess, a hub receiving the sleeve, and a locking device mounted on the hub at a point between the ends of the spindle and engaging the recess of the sleeve and permitting the hub to be removed without detaching the sleeve from the spindle, substantially as described.

5. In a device of the class described, the

combination of a spindle, a sleeve extending longitudinally of the spindle and capable of rotation and forming an axle-box, said sleeve being provided at one side with a longitudinal key or enlargement, a hub havingagroove receiving the key or enlargement of the sleeve, and a locking device mounted on the hub and engaging the sleeve and permitting the hub to he removed without detaching the sleeve from the spindle, substantially as described.

6. In a device of the class described, the combination of a spindle, a sleeve permanently mounted thereon and forming an axlebox and provided at one side with a key or enlargement and having a recess at the opposite side, a hub provided with a groove to receive the key and having a recess at the opposite side, said hub being closed at the outer end, a block or barv mounted in the recess of the hub and adapted to engage the recess of the sleeve, a stem connected with the block or bar and extending through the hub, and a spring arranged within the recess of the hub and engaging the block or bar, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
